Patent GB-169219-A (GB)
Title: Improvements in means for controlling and actuating machines and apparatus
IPC: G01L7/16
Filed: 1920-06-10
Abstract: 169,219. Gauldie, K.. June 10, 1920. Gearing for stopping and starting machinery.- Comprises means for controlling a machine or apparatus in accordance with the magnitude of the pressure applied to a confined mass or aggregate of easily-deformable substance which is solid or possesses the properties of a solid in such degree that it will not leak through a small orifice, the hydrostatic or similar pressure existing in the said mass being utilized to control ther machine either directly or through a relay. As applied to means for preventing the overloading of a crane at different radii, the hoisting rope is secured to a sliding member U containing the easily deformable mass C, which may be indiarubber, so that the pressure on this mass is proportional to the load. This pressure is transmitted, by means of liquid in a flexible receptacle B, to a pressure-gauge on which the pointer can make contact with two spring-controlled contact arms P bearing against stops Q at points corresponding to loads of, say, 5 and 10 tons. These contact arms are in circuit with the solenoid of a circuit-breaker 0 and the two parts of a switch S operated in accordance with the radius at which the load is suspended. The result is that the circuit-breaker opens the main motor circuit if the load exceeds 10 tons at any radius, or if a load of over 5 tons is traversed beyond the 50 feet radius. In a modification, the pressure of a liquid is transmitted, as through the pipe A and the receptacle B to the easily-deformable mass C which acts on a spring or weight-loaded piston, so that when the liquid pressure exceeds a predetermined maximum the piston is operated against the spring or weight and releases a weight which operates a motor switch, trip valve, or other mechanism. This piston may control, directly or indirectly, the cut-off and discharging gear of an automatic machine for weighing predetermined quantities. Instead of using a radius switch for a crane the load on a single small piston may be controlled in accordance with the radius of operation so that at a large radius the piston lifts at a low pressure and at a small radius the piston lifts at a higher pressure. Specification 151,130, [Class 106 (ii), Dynamometers &c.], is referred to.

Title: Improvements in methods of and means for measuring and regulating the tension or thrust between roll stands in continuous rolling-mill trains
IPC: B21B37/16
Filed: 1962-04-25
Abstract: 976,156. Automatic control of rolling mills. SCHLOEMANN A.G. April 25,1962 [April 26, 1961], No. 15710/62. Heading G3R. The transit times of rolled stock through successive stands of a rolling mill are measured by counting electrical pulses so that adjustments can be made to remove longitudinal tension or compression in the stock. As shown, entry of a billet 4 into rolls 2, 3 of a first rolling mill stand 1 results in a change of current to driving motor MW1 so that a relay 10 is actuated to open a gate 11 and allow electric pulses from a source 12 to operate a counter 13 until change of current to motor MW1, when the billet leaves the rolls, causes relay 10 to reclose gate 11. The count, which represents the time for the billet to pass through stand 1, is displayed by a meter 14. In a similar manner a count representing the time for the billet to pass through rolls 7, 8 of the next stand 6 is displayed by a meter 20. If the rolls of stand 6 are running at such a speed as to take up the billet without longitudinal tension or compression the times will be equal, but otherwise the speed of driving motor MW1 and/or the position of roll separation setting motor MA1 are adjusted either manually by observing the meters, or automatically by a difference computer 22, to restore equality of times and eliminate tension or compression Alternatively the speed of driving motor MW6 or the position of separation setting motor of stand 6 may be controlled. In a multi-stand mill the stands at which detection and/or correction is made may be switched sequentially to cover all the stands of the mill.

Patent GB-165322-A (GB)
Title: Manufacture of resinous substances
IPC: C08G8/28
Filed: 1920-06-10
Abstract: Resins are obtained by condensing the ar-tetrahydronaphthol or mixture of ar-tetrahydronaphthols, obtained by alkali fusion from technical tetrahydronaphthalene sulphonic acid, with an aldehyde with or without the aid of a condensing agent; the resins may be rendered fast to light by treatment with acidylating, alkylating, or aralkylating agents.  According to examples, ar-tetrahydronaphthol and 80 per cent formaldehyde are boiled together, or heated in an autoclave to 110-115 DEG  C., or heated to 60-70 DEG  C. in the presence of a little hydrochloric acid, ammonium chloride, or potassium hydroxide, and the resulting viscous products washed and dried; these products are further treated with acetic anhydride, or with ethyl bromide and caustic potash.  In other examples acetaldehyde is employed and the resin obtained heated with benzoic anhydride.  For formaldehyde and acetaldehyde may be substituted their polymers or substances which form an aldehyde.  The products are clear brittle masses, soluble in alcohol, benzene, dichlorbenzene, linseed oil, and turpentine.
Patent GB-359923-A (GB)
Title: Treatment of zinciferous materials containing cadmium
IPC: C22B1/08
Filed: 1930-05-22
Abstract: Zinciferous material, particularly flotation concentrates containing cadmium, is heated with regulated amounts of a chloridizing agent and water to volatilize the cadmium as chloride substantially all of the zinc being retained in the form of oxide.  Lead if present will also be substantially eliminated. The conditions of heating required are those that prevail in blast roasting, such as intensive heating of short duration and the removal of the gaseous products of the operation from the sinter so as to inhibit condensation of the metal chlorides therein. Flotation concentrates are first subjected to a desulphurizing roast so as to leave preferably no more than 2-3 per cent of sulphur in the product, but more sulphur may be left behind for combustion during blast roasting.  The chloridizing roasting may be carried out in a Dwight Lloyd sinter machine, the material being mixed with coal or other combustible agent and any appropriate chloridizing agent and a porous bed of uniform density comprised of sized lumps being desirable.  A soluble chloride may be used in aqueous solution, the moisture content of the charge being adjusted to 10-30 per cent.  The amount of chloridizing agent should be slightly in excess of that required to convert the contaminating metals into chlorides, about 2,5 per cent of chloride by weight being added to material containing up to 5 per cent of contaminating metals.  Two or more sintering treatments may be applied with addition of coal and chloridizing each time as in the first sintering.  The volatilized cadmium and similarly behaving contaminating metals may be recovered as fumes in a suitable collector such as a baghouse or an electrostatic precipitator and the sinter may pass through a roll crusher and treated by two screens of 0,5 and 0,25 inch mesh respectively. The "throughs" of the first screen but the "overs" from the second may be used as hearth layer in the sintering operation. Material treated by two sintering operations on smelting gave a product containing over 99,99 per cent of zinc.
